It should be the digestive system as it absorbs the nutrients of the food into your body.
Answer:
Z=26, A = 56, charge +3.
Explanation:
The atomic number is represented by Z. Is equal to the total number of protons that the atom has. Z=26.
The atomic mass is represented by A. The number results from the total sum of protons and neutrons of an atom. Both particles have a weight of 1 uma, are in the nucleus and give the mass to the atom.
Mass number (A) = atomic number (Z) + number of neutrons (N)
A = 26 + 30
A = 56
The net charge of the atom can be calculated by subtracting the negative charges from the positive ones. The positive charges come from the protons and the negative ones from the electrons.
26-23=3
This iron ion has a positive charge +3.

Hello. You forgot to replace the map needed to answer that question. The map is attached below:
Answer:
B) west to east
Explanation:
The letter H on the map represents an area with high air pressure, while the letter L represents an area with low air pressure. As in the areas of lower temperature or colder the pressure is greater, the wind leaves these areas and goes towards those of higher temperature, which present less pressure. For this reason, we can say that the wind is moving from west to east.
The greater the pressure difference between the regions, the greater the wind speed, and in these situations, strong winds or winds can occur, which are given different names, depending on the location: hurricane (Caribbean), tornado (USA), typhoon (Asia).
